Risk Assessment for Renewable Energy Penetrated Power Systems Considering Battery and Hydrogen Storage Systems

Energy storages can significantly relieve the pressure of the power system brought by a large amount of renewable energy generation. Under this situation, the risk assessment method becomes critical. In this paper, an explicit model for diverse energy storages with battery and Hydrogen Storage Systems (HSS) is built. Further, an optimal load shedding model by utilizing the sequential Monte Carlo (SMC) method is proposed to assess the risk of the power system with diverse energy storages. Then, the proposed method is test on a power system which is adapted from the IEEE 24-bus system. The numerical results show that diverse energy storages can improve risk assessment results of the power system.
